Rush, like Ann Coulter, is so intelligent that often they will make a statement of sarcasm to make a point and it will go right over the head of less intelligent people. That is what happened to Ann on her John Edwards statement last year.
Rush is so far above liberals that he can tell a story, they will take it the wrong way because they are too dumb to get it, then they will spin it to try to make him look bad.
He can be real funny if you can get the idea behind him.
